because it is possible to have on top of the standard 
blas/lapack the specialized ATLAS version for the
specific processor.

Putting the dll's in /usr/lib/lapack
and adding that at the end of PATH allows
to put the atlas versions in /usr/lib 
and they will take precedence over the PATH.

On other unix systems this can be managed with 
symbolic links but on windows is it not possible.
The workaround was defined by the previous lapack 
mantainer James R. Phillips and I decided maintain it.
